Technical Information

Our new B'TWIN ULTRA frame is derived from the Evo Vario concept. Aluminium is an ideal choice for obtaining an excellent propulsion-to-comfort ratio. The variable thickness tubes considerably reduce the weight and ensure excellent performance on all surfaces, even very rough terrain. The design is aerodynamic, the cabling is integrated into the frame and the rear brake is positioned under the chainstays. This frame is UCI-approved. Total weight: 1400 g in M.
Our new B'TWIN ULTRA Evo Vario fork is mounted exclusively on the B'TWIN ULTRA Evo Vario frame. The combination of carbon and aluminium offers perfect synergy between the B'TWIN ULTRA Evo Vario frame and fork. We have achieved a filtering effect on very uneven terrain such as cobblestones. Aerodynamic design with brake located as close as possible to the fork. Total weight: 550 g in L .

Response of the brand
Hello Sudeesh, 

Thank you for taking the time to give us your feedback. The Triban 540 and Ultra have the same 105 components. However, there is a price increase because ultra has a different racing frame geometry with internal wiring. The bike also has the rear brakes place near the crank than the traditional location to increase the efficiency of the braking.

Ultra 700 105 11 speed
Used for 2 to 8 weeks
Grey green is somehow looking like blue black. May be I am color blind. The listing price in India is ridiculous for a 105 11 spd as other major manufacturers also offer bikes with similar specs at same price. BTwin should be affordable not out of reach. I would have bought it in a blink if you guys really offered ultra 720 ultegra at this price
Neglection as ultra 720 af is listed as ultra 700
